In 2010, the United States National Research Council released a report on reforming the NIJ, and identified issues with its independence, budget, and scientific mission. While it considered making the NIJ separate from its current department, Office of Justice Programs, it recommended retaining the NIJ within the OJP but giving it increased independence and authority through clear qualifications for its director, control over its budget, and a statutory advisory board. It also recommended that the NIJ: (1) a focus on research rather than forensic capacity building activities,(2) increase funding for programs for graduate researchers, (3) increase transparency, and (4) do periodic self-assessments.[7]

NIJ is focused on advancing technology for criminal justice application including law enforcement and corrections, forensics, and judicial processes, as well as criminology, criminal justice, and related social science research. Much of this research is facilitated by providing grants to academic institutions, non-profit research organizations, and other entities, as well as collaborating with state and local governments. Areas of social science research include violence against women, corrections, and crime prevention, as well as program evaluation.[8]

Grants for technology development help facilitate research and development of technology and tools for criminal justice application, which is a need that the private sector is otherwise reluctant to meet. NIJ also supports development of voluntary equipment performance standards, as well as conducting compliance testing.[3] Areas of technology research and development include biometrics, communications interoperability, information technology, less-lethal technologies (e.g. tasers), and officer safety including bullet-proof vests. Crime mapping and analysis is a topic that includes both technology and social science (geography) aspects. The National Law Enforcement and Corrections Technology Centers, which are located throughout the United States, play a role in law enforcement technology development, testing, and dissemination.[8]

A major area of research and support is for forensics and the President's DNA initiative. The Federal Bureau of Investigation developed the Combined DNA Index System (CODIS) system as a central database of DNA profiles taken from offenders. In the late 1980s and 1990s, all of the states and the federal government required DNA samples to be collected from offenders in certain types of cases. The demand (casework) for DNA analysis in public crime laboratories increased 73% from 1997 to 2000, and by 2003, there was a backlog of 350,000 rape and homicide cases. In 2003, President George W. Bush proposed the Advancing Justice Through DNA Technology initiative, which would include $1 billion over five years to reduce backlogs, develop and improve capacity of state and local law enforcement to use DNA analysis, support research and development to improve the technology, and additional training for those working in the criminal justice system.[10]
